Firefly Boom

Fireflies in a Jar by Jamelah E

Bridge Michigan shares that Michigan is seeing more fireflies than usual this year, thanks to an early spring followed by drought-like conditions:

Michigan families should enjoy them while they can, says Ben Pfeiffer, founder of the nonprofit organization Firefly Conservation & Research, who projects a continued decline in the bugs. The numbers seen in Michigan skies this summer, Pfeiffer warns, are “likely the best that it’s ever going to be.”

This summer’s lightning bug explosion is a result of drought-like weather preceded by warmer Spring conditions. This matured larvae into adult fireflies earlier. It’s during the adult stage, which lasts about two months, that fireflies show off their distinctive bioluminescence.

The long-term decrease in the firefly population is caused by an increase in light pollution and pesticide use. Fireflies mate through glow patterns and require a dark environment. Bright white LED light interrupts the fireflies’ ability to see each other. Pesticides used outside, especially in soil, to kill insects like spiders or beetles can harm fireflies as well.

Jamelah shared this photo waaaaay back in 2005 & I thought it a great one to bring back. She wrote “I think deep down I’m still 5, because last night I had an incredible amount of fun catching fireflies,” and honestly SAME every time I do it!! See more in her Summer gallery on Flickr & read/see her work at Jamelah.net.
